Hi!

I’m John (at right, on Netherlands TV)1. I’m a writer and app software engineer. I grew up in Southern California and I’ve worked in Northern California as a programmer and journalist.

I now live and work in London, where I operate a small consultancy, JupiterJazz.io, making native iOS and Android apps for clients. Although I’m pretty good with Apple’s new language Swift, these days we are mostly interested in working with React Native.

Software

My programming experience stretches back to my youth, during which I was obsessed with Commodore Amiga computers and earned extra credit from a kind math teacher after he discovered I had spent his trig lectures writing games on the class’s VAX mainframe about dudes with swords fighting wizards.

Lately I’ve been working the most with React Native and other modern JavaScript. I also do stuff with Unix, Web servers and databases.
